Dosen, R. | Gagrcin, M. | Prodanov, J. | Lalic, M.
The present investigation aims to answer on some epidemiologic questions, such as, new potent way and source of infection in the pigs from sows that were not vaccinated and also way animals develop disease even through they have been vaccinated. The most important sources of infection are cats, dogs and foxes especially if the farm was not palisad. The chance is high that some of pigs may become infected in the absence of antibody when they arrive in the herds vaccine against pseudorabies. Improperly administered vaccines may fail to induce the expected immune response in healthy animals.
